"0 all whom it may concern:

Be it known that I, HENRY BOUNDS CARY, a citizen of the United States, residing at the city of Los Angeles, county of Los Angeles, State of California, have invented new and useful Improvements in Word- Connting Attachments for Type -Writing Machines, of which the following is a specification.

My invention relates to improvements on the mechanism, set forth and described in U. S. Patent No. 701,840, issued to me June 10, 1902, and the objectof this invention is to simplify and improvethe attachment disclosed in that patent. In that mechanism I arrange to operate the counting mechanism of the words by the spacer bar. In practice I find that it requires a full stroke of the spacer bar inorder vtocount a word and does not require a full stroke of the spacer bar to space a word in writing. It frequently happens that an operator will space a word without a full stroke of the spacer bar and therefore will not count the word.

To obviate these defects is one of the ob- V jects of my present invention, and I do this by operating the counting mechanism as to the words by the lever which operates the type bar which prints the first letter of each word.-

In my said patent I use two counters, one for words, and one for figures and characters counted aswords. In my present improvement I use only one counter which is operated by two dogs which may be caused to. move together or singly. The dog operated by striking the first letter of a word operates the counting mechanism and is held in an inoperative position thereafter until released by the operation of the spacer barand while in its inoperative position it doesnot interfere with. the operation of the other dog. In, my former patent the, cam bar was, inside the rocking lever. frame. In my present, improvement said bar is outside the lever frame as it takes lesspower to operate it outside than inside said frame.

The above and other objects and the novel featuresof my invention will be apparent from the followin description taken in connection with the. drawings inwhich similar reference characters indicate the same parts in the, several figures of the drawings in which Figure l is a side elevation of one of the base bars by means of which my attachment is secured to the frame of a typewriting machine, showing the parts carried by saidbase bar; Fig. 2 is a view of the parts shown in Fig. l in another position; Fig. 3 is a bottom plan view of the parts shown in Fig. 2; Fig. 4 is an edge elevation of the counter mechanism and its actuating levers viewed from the keyboard side of the machine; Fig. 5 is a side elevation of the parts shown in Fig. 4, from the machine side; Fig. 6 is a side elevation of the parts shown in Fig. 4 from the opposite side to that shown in Fig.

v 5; Fig. 7 is a section on the line 7-7 of Fig.

5; Fig. 8 is a bottom plan of the parts shown in Fig. 7; Fig. 9 is a bottom planview of my attachment showing the same in position on a typewriting machine indicated in light lines; and Fig. 10 is a section on the line XX of Fig. 9, looking in the direction of the arrows and with the parts in their upright position.

In the drawings 10 and 11 are base bars.

having holes 12 (see Figs. 7 and 8), extending therethrough to receive the screws 121 which connect the attachment. to the bottom of the typewriting machine, as shown in Fig.

9. In the ends of the base bars nearest the oneanother to raise or lower the fulcrum rod 17 which is carried by these blocks. One end of the fulcrum rod 17 is held in one block 14 by a set screw 18 and the other end of the rod passes entirely through the other block 14 and throughthe base .bar 11 and a similar set screw holds this end, of said rod .in place.

The attachment illustrated in the drawings is used on an. Underwood typewriter. A lever bar 19 is rockably mounted at one end on the fulcrum rod 17 and a screw .20 passes through an elongated slot 21 in the bar 19 and adjustably secures thelatter to the inner sideof the base bar 10. The other end of the bar 19 is bifurcated and straddles a part of the. frame of the typewriter. at 191,

see Fig. 9. A link bar 22 is provided with means at its upper end to connect it to the elevating bar of the shifting mechanism of the typewriter which shifts the type from lower to upper case printing position. The lower end of the link bar 22 carries a pin 23 which enters a slot 2-1 in the outer end of one element 25 of a compound lever which forms part of the actuating mechanism of cam shaft 26. The shaft 2-6 carries a series of cams, see Figs. 2, 3, 9 and 10. Figs. 1 and 2 show one of the cams 27 in two different operative positions. These cams are arranged so they will be struck and depressed by key levers carrying a figure or character counted as a word, thereby actuating the shaft 26 which carries the cams.

A stud 28 pivotally supports the element 25 on the bar 19 and the other end of the element 25 carries a pin 29 that enters the slot 30 between the ends of the other element 31 of said compound lever. The outer end of the element 31 is rockably mounted on the rod 17 and spaced from the bar 19 by a washer 32. The inner end of element 31 has an elongated slot 33 therein and the outer end of the crank 3% on the cam shaft 26 extends into this slot 33. The cam shaft is rockably mounted in the outer ends of the arms 261 of a swinging bail A, (see Figs. 9 andlO) the inner ends of said arms 261 being rockably mounted on the fulcrum rod 17 and the outer ends being connected by the cross pieces 262. Suitable collars 171 and 172 hold the bail A in place on the rod 17 and a coil spring 263 surrounds the rod 17 and has one end 26% bearing against the under sides of the cross pieces 262 to yieldingly press the bail upwardly and serves to restore the bail after the same has been depressed and released. This lower-to-upper-case adjustment of the cams provides for the counting of those upper case characters which count as words and for the elimination from the count of those characters which are not given the value of a word.

Referring to Figs. 5 and 6, the end of the shaft 26 opposite the crank 3 1 is mounted in a slot 35 in the inner member 36 of the cam shaft rocker arm which is pivotally mounted on the fulcrum rod 17. The outer member 37 of this rocker arm lies on the outside of base bar 11 and the two members 36 and 37 are connected by a body member 38 which passes across and below base bar 11.

The rocking frame B, see Fig. 9, consists of two side bars 391 pivoted between their ends, a front bar 392 depressible by the word spacing frame W to restore said frame to its initial position after the frame has been rocked by an alphabet key lever to actuate the counting mechanism to count a word. The backbar 39 of the rocking frame B is received in a notch at the free end of the inner member 40 of the rocking frame rocker arm pivotally mounted on the fulcrum rod 17. The outer member ll of this last rocker arm lies on the outside of the base bar 11, but inside the outer member 37 of the cam shaft rocker arm. A body member -11 (see Figs.

end of the bail extends outside of the frame B and the cam shaft 26 is mounted at the rear of the back bar 39, and hence lesspower is required to actuate the bail. The spring 393 carried by the fulcrum rod 17 frictionally engages one of the side bars 391 of the frame B and holds it either in its depressed or elevated positions.

A standard 42 has its lower end secured to the base bar 11 and is bent outwardly and upwardly and at its upper end carries a counting cylinder 42 of any approved make. The counter has a shaft 43 which projects from the inside thereof and carries adisk 44 provided with a plurality of pins 45 equally spaced apart around the periphery of the disk. A detent arm 16 is pivotally mounted at the upper end of the standard t2 and has a bill 47 which is yieldingly held in engagement with the pins 4-5 by a spring 48. This bill permits the disk carrying the pins to rotate toward the pivot of the arm and prevents rotation thereof in the opposite direction.

An upwardly extending bar (see Figs. 1, 5 and 6) is rockably mounted on the fulcrum rod 17 and adjustably connected by screw 49 to the outer member 37 of the cam shaft rocker arm. This adjustment is so that the upper end of the bar 50 can be positioned closer or farther from the counting cylinder 42. A bill-shaped dog 51 is rockably mounted at the upper end of the bar 50 and a spring 52 connected to the dog and bar holds the dog in such a position that when the bar 50 is rocked toward the counter, the end of the bill engages a pin 15 and rotates the disk t4: one tenth of a turn. hen the bar is retracted the spring permits the bill to ride up over the next pin below it v and move back out of the path of the pins.

An upwardly extending bar 5% is rock ably mounted on the fulcrum rod 17 and its lower end is adjustably connected to the outer member 41 of the rocking frame rocker arm by a screw 53. This adjustment is such that the upper end of bar 54 can be positioned closer to or farther from the counter -12. A dog 55 is rockably mounted on the upper end of the bar 5% and has a nose 56 which projects to that side of the dog nearer to the pins of the counter and is angularly disposed to the body of the dog. The dog is held in such a position by the spring 57 'that'when the back bar 39 is struck and depressed by an alphabet key lever, and the bar 54 is rocked, the body of the dog passes beyond the ends. of the pins but the nose engages a pin and rotates the disk one tenth of a turn and then stops until retracted from within the path of the pins when the spacing frame W strikes .the front bar 392 and rocks the frame B to its initial position. This rocker frame may be so adjusted that it will remain in its alternate positions until acted upon by either a proper key lever or the spacer frame, as the key levers after the first one struck, do not act upon the frame B, since its next operation must be effected by the operation of the spacer frame at the end of a word. When bar 54 is retracted the spring 57 permits the nose to ride up over the next pin below it and move back out of the path of movement of the pins. It will be understood that the pins are held against backward movement by the bill of the detent46. A slotted guide plate 58 is secured to standard 42 and guides bars 50 and 54 in their movements toward and from the counter 42.

Vhen the first letter of a word is struck the rocking frame B operates bar 54 to carry the nose of dog 55 into engagement with a pin on the disk 44 and to move disk 44 one tenth of a turn and then to pass within the path of movement where the nose remains until the swinging frame B is released and retracted. The nose then returns to its normal position. When a numeral or sign that is counted as a word is struck the cam shaft 26 is operated and bar 50 moves dog 51 into engagement with a pin on the disk 44 and moves the disk 44 one tenth of a turn when the bar retracts the dog back to its normal position. It will thus be seen that the words and the characters counted as words are all counted on the same counting device, there by simplifying the mechanism of my beforementioned patent. By the use of a compound lever in actuating the cam shaft so little power is required that an operator can hardly detect from the touch of the keys when my attachment is on a machine.

In the mechanism described herein the counting mechanism is constructed on the decimal system. If another counting'mechanism should be used in which a different system would be used, the bars carrying the dogs would be applicable thereto by being so moved that a forward movement would turn a counting disk of the counting mechanism to indicate one word. counted. It will be seen that by this mechanism each word is counted'when the first letter thereof is struck and that the nose of the dog which is actuated bythealphabetkey levers moves within the path of movement of the pins of the counting-mechanism as it counts the word and islocked there 'until released by the spacer bar or frame of the machine, and

r thatzwhem in such; position it does: not interfere with the dog actuated by the key levers of the machine carrying characters usually counted as words.

Referring to. applicants former patent N 0. 701,840, the rocking frame 12 in said patent performs the same functions as rocking frame B in the present invention, and

ithe swinging bail 11 of said patent the'same as bail A in the present application. The cams 33, of the patent corresponds to cams 27 of this application, and rock shaft 22 of the patent to shaft 26 of the present application. -The shifting mechanism on left hand-of counter of patent represented by elementsmarked 24, 25 and 26 is replaced by 'elements'22, 31, 25 and 19, shown in this application. The transmission of motion of the rocking frame 12 to the register 35 by element 37 and motionof swinging bail 22 to register 36 by element 31 in above pat- I cut is accomplishedin this application from frame B and bail A to a single counter 42 by elements marked35 and 54, and 35 and 50, respectively.
